Winner NYC METRO architect/developer competitionULI Workforce Housing Design Award

Located in the heart of Harlem, the nation’s largest African American community, the building proudly celebrates its African culture. The brick patterns and colors were inspired by the Kalahari African tribal patterns painted on desert homes

The sustainable affordable and market-rate development creates workforce housing with generous amenities and green technologies for families of diverse backgrounds and income levels.

PASSIVE SYSTEMS• Exterior Wall: DOE 2 modeling• High R values• Low air infiltration• Windows: AW 70, minimize air infiltration• Glazing: low – E, Min. 75% VT, U .30 (less solar heat gain)• Roof: R30 min, planted roofing system• Local Resources: 500 mile radius• Materials Selection: recycled (steel and concrete), post-

industrial and rapid renewable (bamboo flooring)• Low VOC Materials (carpet & paint)• Improved Indoor Air Quality

ACTIVE SYSTEMS• Heating and Cooling: open loop standing column

geothermal exchange (design concept: 20 wells, 700 tons)

• Photovoltaics: 25-30 KW• Heat Recover • IAQ: Fresh air filtered & conditioned

(3x normal air exchange)• High Efficiency: Energy Star Fixtures, Heat Pumps,

Condensing Boilers• Motion Detector Light Fixtures• Digital Sub-metering: programmable thermostats

BUILDING ENVELOPE DESIGN• Reduced thermal bridging in walls • Cardinal Low-E2-170 glass with U-0.29 (center of

glass), shading coefficient 0.43 .37 solar heat gain coefficient

• 70% visible transmittance or glass with equivalent properties in terms of U-factor & shading coefficient

• Airtight wall construction & airtight windows (documented field tests).

• Planted roof

STRUCTURAL SYSTEM• Steel: 95% recycled content, local• CMU: recycled content, massive (high STC), local• Pre-cast Concrete Plank: recycled content, fast

installation, local

The financing was designed to protect the interests of long-term Harlem stakeholders by making 50% of the units affordable and 50% market rate (the first time in New York City) with a 50% preference for existing Harlem residents.

The undulating massing is a creative interpretation of the New York City zoning code to provide alternating rhythm of tower and wall along the building’s 300-foot football-field length.

Harlem’s new, green 249-unit mixed-use, mixed-income condominium reflects the richness and variety of Harlem's vibrant urban African-American cultural fabric. The design was unanimously approved on the first vote by Harlem’s local community board #10 and the New York City Planning Commission.

TYPICAL UNITSAlmost zero circulation planning and abundance of windows increases efficiency and daylight in units. More space for less money with less construction cost.

Interiors feature high performance windows and lighting fixtures, bamboo flooring and cabinets manufactured with sustainable materials.

3D BRICK PATTERN STUDY TYPICAL CAVITY WALL DETAIL

New York State Energy Research and Development Authority (NYSERDA) provided a grant for the modeling, testing and performance of the energy saving cavity wall that performs better that any similar wall construction in the New York City. The building uses recycled steel and recycled concrete and achieves USGBC LEED Gold Standards.

OPTION 1: NYS DOE funded thermal analysis of brick wall design
